5% WMZI EMERSON A. BOLEN, OF 'MORRIS, ILLINOIS.

FLUID-DISCHARGING DEVICE.

Application filed April 15, 1911. Serial No. 621,419.

To all whom it may concern Be it known that I, EMERSON A. BOLEN, a citizen of the United States, residing in the city of Morris, in the county of Grundy and State of Illinois, have invented certain new and useful Improvements in Fluid- Discharging Devices, of which the following is a specification.

The object of this invention is to provide cans, and in particular oil cans, with a combination attachment which constitutes a ready and convenient means for discharging the contents of the "can from the filling nozzle without inverting the can or otherwise giving occasion for spilling the contents, and which may be attached to, or

removed from, the can in the same manner as the cover for the filling nozzle, so as to be interchangeable with said cover.

In the drawing, showing the preferable form of my device, Figure 1. is a perspective view of an oil can with my device attached thereto; Fig. 2. is aperspective view of the same can with my device removed therefrom, and a common screw-cap attached in its place; Fig. 3. is a sectional view of my attachment in the plane of the several pipes forming members thereof; and Fig. this an enlarged detail of the view shown in Fig. 3.

Referring to the drawing, can 5 is pro vided with filling nozzle 6, adapted to be closed by screw cap' 7 Another screw cap 8, likewise adapted to screw on to nozzle 6, is provided with a central elevation .or boss 9, into the top of which is entered blow pipe 10, and through the side of which passes discharge pipe 11, having a horizontal arm 12, ending in discharge nozzle 13, and a vertical arm 14, reaching, as near as may be, to the bottom of can 5 when cap v8 is fully screwed down on nozzle 6. The lower end 15,0f arm 14, is preferably cut off at a slant in order that touching of the bottom of can 5 by end 15 will not prevent the oil in can 5 from entering pipe 11. Boss 9 is also provided with vent 16 adapted to be closed by the thumb of the person operating my device. By means of spider 17 a ball 18, of proper material, such as aluminum, is held suspended immediately below the lower end 19 of blow pipe 10, in such a manner that it will form a valve adapted to admit of air being blown into the can through pipe 10, but to be closed through the air pressure Specification of Letters Patent.

within the can whenever the operator ceases to force air into the can, ball 18 in such case being lifted so as to close pipe 10 through the airpressure from within the can. The practical operation of my device is as follows :Screw cap 7 is removed from nozzle 6 of filled can 5 and cap 8 with the parts attached thereto, is screwed on in its place. The operator thereupon places the lamp or other vessel to be filled under discharge nozzle 18, places one of his thumbs over vent 16, and blows air into blow pipe 10, either by means of his mouth, or by other suitable means, such as a compression bulb. The pressure thus introduced into can 5 will force the oil therein contained up through discharge pipe 11, into the lamp or other vessel provided for its reception. Whenever the operator ceases to force air into the can, the pressure of the air already contained therein will act upon ball 18, so as to close the lower end of blow pipe 10, thereby preventing escape of air through said blowpipe 10. With the continuing delivery of the oil, or other fluid contained in can 5, through discharge pipe 11, the air pressure in the can gradually decreases, finally allowing ball 18 to drop "down onto spider 17, where it will be held in place immediately below the lower end of the blow pipe 10. If it is desired to stop'the fiow of oil, or other contents of can 5 before the pressure of the air therein containedis exhausted, this may instantly be accomplished by removing the thumb of the operator from vent 16, thereby allowing the air in the can to escape, and thus stopping all pressure on the fluid in the can.

I claim: y

In a fluid discharging device, the combination of a screw cap adapted to close a fluid container, with a hollow boss projecting above the top of said screw cap, and provided with a vent in its side; a d scharge pipe, adapted to extend into the fluld to be discharged and penetrating the side ofsaid boss; a cap for said boss having its center depressed so as to form a cage for a ball; a ball in said cage; and a blowpipe entered into said cap above said cage; substantially as and for the purpose set forth.
